A spring 43 surrounds the shaft of screw 41 which serves to hold the screw adjusting screw 41 contacts with stop member 44 (Fig. 1) which is pivotally' mounted at 45 in the frame of the machine. A spring 46 is connected at one end to stop member 44 and is connected with the frame at the other end. Sprin 46 serves to hold stop member 44 rotated into the osition shown in Fig. 1, the rotation of the stop member 44 being limited by a pin' The end 47 of lever 39 has "spring 48 connected thereto, which :spring is connected at its other extremity to the cement disk 'casing'21. The spring ture 49 in table 50 near to 48 serves to rotate the arm aperture 52 in table 50 in a 39 about its pivot 37 through aperthe disk 18. The extent of the rotation o f'arm 39 caused by spring 48 is 'adjustably limited by screw 41 contacting with the stop 44. V

Another brush 51 extends up through position sli htl in front of and below the disk 18. rus 51 is carried in spring clips 53 on the end of lever 54 which pin 55. The pin 55 is carried in bracket- 56 which is riveted as shown at 57 to plate 58. To one end of the lever 54 is connected a spring 59, the other end of which'is attached to a hook 60 carried by the plate 58. J uxtaposed to the sprin 59 is a screw 61 which 1s threadeclninto a %lock 62 carried by hook 60. A spring 63 surrounds the shank of the screw 61- so as to prevent free rotation of the screw relative to the block 62. The

A screw 64 isprovided in the end of lever 54 which limits the extent of the rotantion of the lever 54 in the direction opposite to that caused by spring 59.

The plate 58 which carries brush 51 and its associated parts fits in an opening in table 50 and is removably held therein by latch 66 which cooperates with a ledge on the block 65 which is. riveted to the plate 58. The latch 66 is mounted for rotation on the screw 67 extending into table 50. On rotation of the latch 66 about the leased and may bev ifted from the table 50 together withthe brush 51 and its associated parts.

At 68, in Fig. 1, is indicated the base late which is bolted to the base member 3. %ase plate 68 carries member 70, which tubular member 70 forms a support for; the cement disk casing and also serves as admin for excess cement escaping from. the disk 18 which cement is carried into the waste tank701.

Frame 71 is fastened at the front side of member 70 by means of screws 72. Screws 74 serve to'fasten plates 73 to the lower side of frame member 71. The plates 73 form together with the projecting portions 75 of the frame members 71 a pair of slots 76 in which slide 77 moves. The slide 77 is fastened to table 50 by means of bracket 78 and screws 79. The slide 77carries rack 80 which operates with pinion 81 carried 82 which has a manually opera le knob 83 at its end.- Operation of the knob 83 effects, throu h the rack and pinion, the adjustment 0 the table 50 relative to the cement disk 18.

After adjustment,'the table is locked in position b means of avsleeve 87 threaded on to the s aft 82. U on turning the sleeve 87 the shaft 82 is rawn to the left as shown in Fig. 2 whereupon conicalhead 84 on the end of shaft 82 is drawn into the The frictional ber 84 with the surface of the recess 86 locks the shaft. 82 a ainst rotation so that the table 50 will be held inits adjusted position.

In order to prevent the table 50 from being brought into too close proximity to the disk 18, a latch 88 is rovided. Latch 88- is fastened by means 0 screw 89 to the slide 77 as shown in Fig. 4. Thelatch 88 has a projecting end operating in the notch 90 in plate 73. The projecting end of the latch 88. is held in position in notch 90 by means of spring 91 connected to the latch by web 69, the tubular,

pivot 67 from the po- 2 the plate 58 is reand to the slide 77 as will be seen from Fig. 5. The motion of the table is limited by the projecting end of latch 88 cooperating with the notch 90.'- The latch 88 has a bent over end 92 projecting below the lower end of the table 50 by which the projecting end of the latch 88 may be manually moved from engagement with the notch 90 so that the table may be removed, if necessary. 7

At the right side of the table 50, as shown in Fig. 2, there is positioned a brush 93, shown more particularly in Fig. 3. The

brush 93 is heldto the table 50 by bracket 95 riveted to table 50 and to which bracket the brush is clamped by the bolt and thumb screw 96.

Beneath the lower edge of the table 50 there is positioned a catch pan-97 which is removably mounted on the member by means of brackets 98. The pan 97 serves to catch cement dripping from the lower edge of the table 50.

In the operation of the device the cement disk 18 is set into operation by belt 7 and pulley 8 and the connecting motion transmitting parts. Cement is fed from tank 25 onto the disk 18 through the valved conduit 24. As the cement flows into the disk housing 21 it covers the disk 18 on both sides. As the disk rotates, cement is carried out through aperture 34, the scraper 28 and dam 31 serving to direct the cement along the lower edge of the disk. The scraper 36 serves to divert the cement from the disk on to brushes 37 and 51. The shoe to be cemented is then-placed upon the. table 50 and its side is brought into contact with i the disk 18 and brush 37 and, as the shoe is moved so that various portions of its side is brought into contact with the disk 18 and brush 37, cement is applied thereto. As the shoe is-moved in contact with brush 37 and disk 18, the bottom and shank of the shoe are wiped over the brush 51 which" brush is resiliently held in contact therewith by .mean ofspring 59. After the cement has-been applied. to the shoe any excess cement which may be upon the bottom of the shoe is wiped oil by wiping the bottom across the top of thebrush 93 which, is conveniently located at the edge. of the. table 50, the excess cement 'flowiiig down the table and into the pan 97.

The degree of pressure of the brushes 37 and 51 upon the shoe is controlled by the screw 41 and spring 48 and by screw 61 and spring 59, respectively. The distance be- .tween the bottom of the shoe and the bead of cement applied by disk 18 can be varied 1 by adjusting the table 50 with respect to disk 18 by means of rack and pinion and 81. e i

The brush 37 may bereplaced by moving the stop plate 44 out of contact with the position.

access may be had to the brush 51 and its spring clip 53.
